Things might be starting to get bad for old Newt. Remember, the previous anti-Romney front-runners (Bachmann, Perry and Cain) shared a shelf-life of about 1 month. So Newt's popularity might run out before the Iowa caucus. If so, Ron Paul might end up running away with it and acting as Mitt's main competition for the nomination. If Ron Paul does start gaining some of the front-runner support that Newt has now, chances are he'll keep it. Once you support Ron Paul, you generally don't stop supporting him. That's just the nature of the Ron Paul Revolution.
